Abstract
An on-load tap-changer has a transmission, a motor with an output shaft, and a diverter switch with a drive shaft. The transmission has a cam disk; a drive gear wheel; and a roller coupled to the drive gear wheel. The cam disk is connected the output shaft, which lies on a rotation axis of the cam disk. The drive gear wheel is connected to the drive shaft. The cam disk has an inner and outer contour, which are followed by the roller, and which each have a first region with a constant radius of curvature and a second region in which a distance of a respective contour from the rotation axis of the cam disk changes. During a rotational movement of the cam disk, the roller follows the first region of the outer contour, the second region of the outer contour, and then the first region of the inner contour.
